Contrary to what was first believed, it looks like the newcomer Gigas isn't JACK's replacement after all.
Unlike the previous JACKs, JACK-7 now sports a red mohawk and the grooves in his arms and face illuminate with a greenish glow. He seems to have traded his green camo pants with a brown one similar to his fifth incarnation in Tekken 5: Dark Resurrection, and he looks to be the hardest-hitting he's ever been with his new wall grab and Rage Arts.
Take a look at his gameplay video below.
